COKE BIN.

Application .filed June 17,

This invention relates to an improvement 3 in bins used for storing friable material such' by screening or otherwise must be mainsegregation according to size, which increasestained to secure the most desirable results in the use of said material, and consists of'the' matters hereinafter described and more particularly pointedout in the appended claims. The purpose and object of the invention may be mosteasily described and illustrated in connection with bins-for the storage of coke for use in blast furnaces; but as will be understood, its application is not limited thereto. i i i Coke after its manufacture is screened and segregated into lots or portions of graded size.v It is then loadedinto cars for transport to the blast furnace bins which'should provide a large storage space. To get the benefit of the full storage capacity of bins of any kind, it manifest that: theylmust be substantially emptied before 7 refilling. In the case of the bins in question, however, this has not been practically feasible because in the charging orfilling of anempty bin with coke, the shock due to the great drop from the car above it to the bin floor in the beginning and to the level of the surface of the coke until the bin'is almost full, is so great, that there is considerable breakage of the coke. This breakage also results in the bad effects following from breakage.

To overcome these objectionable results by reducing the drop of the coke, it has been-the practice after the coke bin has been filled .in the beginning, to supply enough cars for transporting the coke to replace the coke in l the bins by filling or charging from-the cars at substantially the same rate that the coke is, withdrawn from the bins. quires the bins to be practically always full to the top. means for shortening the drop from the car to the bin discharge gate and the function of the bin as a store or reservoir for coke disappears. Costs required by the continuous presence of operatives for unloading at the bins and by the continuous switching of the the bins function as stores or reservoirs.

Theobject of the present invention is to provide a construction of bin in which the This in effect re- .ie iis i 2. isa Tl bi this let ineiel a cars'are increased as compared to cases when bin, are preferably inclined at angles slightly 1927. vSerial No. 199,439.

full capacity of the bin as a store or reservoir may utilized and the bin emptied or substantially emptied at intervals without'dair gel of breaking the coke or other friable material from the shock of drop from the car which 1s unload1ng nto the bin and without segregatlon according to size which results from such breakage.

The advantages of the invention will ap pearniore clearly as I proceed with my specie ticatlon. p l

In the drawings: p F1gure 1 represents a section through a bin made in accordance with my invention in a plane transverse of'the tracks above the Figure 2 represents a section through a bin of slightly modified construction wherein the plane of the section is parallel to the direction of the track above the bin. 7 Referring now to that embodiment of my invention illustrated in the drawings and particularly in Figure 1 :10 indicates a coke bin; 11,11indicate tracks for cars above the bin and in position to discharge there-v into; and 13, the girders which support the car tracks and bin. 14, 14 indicate thewall's of the bin which walls are downwardly inclined and converge toward the discharge,

construction.

16 indicates a plurality of spaced partition walls or diaphragms, each eiitending trans versely of the bin and in substantial paralleb ism with one of the downwardly inclined walls 1 14; thereof. Eachpartitionwall 16' (intends from the top or near the top of the bin but stops short of that wall of the bin to which it is not parallel. The several partition walls thus leave a passageway 17 be-- tween their bottom ends and the one wall 14 of the bin. This arrangement thus divides the bin into a plurality of "inclined passage ways 16 running parallel to one inclined wall l lQof the bin from .thetop of the bin towards the other inclined wall 14, witheach passageway 16 communicating at its bot tom end with the passageway 17 running i greater than the angle of repose of the material to be contained in the bin.

walls 14? and provide pass:

of the tracks 11, the coke discharged will fall" witha short dropon one or the'other of the diaphragms or partition. walls 16 andby a comparatively slow movement will run down said wall to the passageway 17 (between-the ends of said diapl ragms and the aroxiinate wall 1 1 of the bin) until that passagewayis -7 filled from the bin gate to the upper level of the bottom end of'thepassageway or passageways that are receiving the discharge ofcoke. The passageways themselves will then fill'to the top of the bin. This method is followed until all of the passageways 16 (and thus the entire bin) are full to the top level. of the bin. In this entire filling movement, the drop from the car to the diaphragms 16 is short is also thedrop from the ends of said diaphragms to the proximate wall of the bin defining the passageway 17, and the movement of the coke down the passageways is in all cases slow and easy. Thus both breakage and segregation are avoided in filling the bin.

/Vhen the bin gate is open for the discharge of coke, from the bin, the coke will first discharge from the passageway 16 nearest the wall 1 1 to which it is parallel; it will next discharge from the passageway 16 next above the first one and so on until all of the passageways 16 have been depleted oftheir contents. This will leave the passageway 17 from which the coke in thebin is last discharged. a

In order to distribute the coke to the top openings of all of the passageways 16, it may be preferred to use shuttle conveyors 18, 18 under each track 11, capable of both endwise and sidewise movement.

In Figure 2 I have shown a slightly modified form of the construction. In this case only one track 11 is supported above the bin 3 length of the track, are in this case arranged transversely of the track. 16 indicates the said diaphragms whiclnasbefore, are arranged parallel to one of the downwardly inclined g'cways it) which run from the top of the bin towards the sliding gates 15 which close'the discharge openings 15 at the bottom of the bin, and

towards the other downwardly inclined wall i l. Those of the diaphragms 16* whose bottom ends are beyond a ,point vertically above the bin gates terminates short of the other downwardly inclined bin wall 14*, leaving a passageway 17 between their bottom ends and said inclined wall and the planes of said diaphragms terminate at points above the bin gates so asto leave a passageway or space 1( above the bin gates.

The operation of filling the bin is substantially as described in the first case, the coke by a short drop falling on the several partition walls 16 and running down them until arrested by one of the bin gates in the cases where said walls end above a bin gate or by theinclined wall 14L providing the passageway 17 in the case of the arrest of said di aphragm walls.

lVhen the bin gates are opened in this case, the discharge will be first from the passageways leadingdi'rectly to abin gate. Afterwards the discharge will be from the'passageway 17* and from the several passageways 16 connected therewith.

jl/Vhile in describing my invention I have referred to several details of-mechani'cal construction and arrangement of parts, it is to be understood that the invention is in no way limited thereto except asmay be. polntedout in the appendedclaims.

I claim as my invention:

1. A binadapted for the'storage of friable material, comprising oppositely inclined, downwardly converging walls, and a pluralityof spaced partition walls substantially'parallel to one inclined wall-of the bin'and extending transversely from the top of saidbin to the oppositely inclined wall.

2. A bin adapted for tliestorage'of friable material, comprising oppositely inclined, downwardly converging walls, and a plurality of spaced partition walls extending transversely of said bin, said partition walls being substantially parallel to one inclined wall of the bin and to each other and terminating short of the other inclined wall.

3. A bin adapted for the storage of friable material, coin 'irising oppositely inclined, downwardly converging walls, a plurality of spaced partition walls extending transversely of the bin and providing a plurality of passageways opening at one end towards the top of the bin and at the other at points spaced from one wallof the bin, said partition walls being parallel to the other wall of the bin, and the two said walls and said partition walls being inclined at an angle somew iat greater than the angle of repose of the material to be stored.

4. In a bin adapted for the storage of friable niaterial, means providing a plurality of downwardlyinclined passageways opening at the top towards the top of the bin, one of said passageways being inclined at an angle to the other a .geways which have their lower ends opening into said one passageway and functioning as a common exit passageway for said other passageways, and the several passageways having walls inclined at an angle somewhat greater than the angle of repose oi the material to be stored.

Intestiniony that I claim the foregoing as my invention, I aflixmy signature this lath day ef'June, A. D. 1927.
